在本实施例的排水结构中，进气阀10包括：阀座1，阀座1内设置有进气腔12，阀口121位于进气腔12的一端，进气腔12的另一端设置有排气口14；阀芯2，可上下浮动地设置在进气腔12内，以打开或关闭阀口121；多个相互连通的连通槽22；多个连通槽22设置于阀芯2的底部；流通通道3；阀芯2与进气腔12的内壁之间具有数条流通通道3，连通槽22与流通通道3一一对应并连通。这样，通过设置多条流通通道3与多条连通槽22，并且使连通槽22与流通通道3一一对应，方便进气时气流流通，增加进气量的同时又具有较好的导向作用。
在一些实施例中，连接头4上设置有安装口411，进气阀10可拆卸的安装在安装口411上。
在一些实施例中，进气阀10安装于排水阀5的最高部位，进气阀10的阀芯2通过自重开启，进气阀在水压产生负压时实现进气功能。
参见图1至图6，阀芯2为圆柱形结构，连通切面21为平面，连通切面21与阀芯2圆形端面的交线为阀芯2圆形端面的切线。
为了提高进气效率，在本实施例的近期结构中，参见图1至图6。
参见图1至图6，在本实施例中，各个连通槽22的一端分别用于与各个连通槽22相对应的流通通道3连通；各个连通槽22的另一端相互连通。
参见图1至图6，在一些实施例中，各个连通槽22均垂直于连通切面21设置，各个连通槽22的延伸长度均相等。这样，能够使得气流经过最短的路径，减少气流流动对进气阀10的结构的影响。
本实施例的进气阀，连通切面21上可设置有流通槽，流通槽的一端与阀口121连通，流通槽的另一端与连通槽22连通。
参见图1至图6，阀座1上设置有阻挡部13，阻挡部13设置在阀座1的排气口14处，阻挡部13将阀芯2限位在进气腔12内。
阀座1包括：第一阀座体101，阀口121设置于第一阀座体101，第一阀座体101上设有与阀口121连通的进气通道11；第二阀座体102，第二阀座体102与第一阀座体101连接，进气腔12的至少部分设置在第二阀座体102内；其中，第一阀座体101和第二阀座体102之间具有安装槽，安装槽内设置有第一密封件16。
参见图1至图12，排水阀5包括防冻阀芯51、温包52以及与排水管道42连接的防冻阀座53，排水口设置在防冻阀座53的一端，温包52的一端和防冻阀芯51止挡配合，温包52和防冻阀芯51均可移动地设置在防冻阀座53内，以封堵或打开排水口。
在一些实施例中，连接头4采用黄铜、铝合金等金属材料，有较好的导热性能，可较好的将主水管的热量传导到温包52处，从而更准确的防冻，在水温低时及时开阀排水，水温高时及时关闭。非金属材料由于导热较差，不适合作为连接头，不锈钢材质导热相对较差，在作为连接头4材料时，需要验证主水管水温和温包52处温度的温差，否则可能存在低温环境时意外开启的风险。而黄铜、铝合金等导热较好的材质可确保主水管与温包52处温差较低，是较合适的材料。
在一些实施例中，进气阀10与连接头4通过螺纹等可拆卸结构连接，实现可更换的结构。
本实施例的排水结构集成有进气阀10、排水阀5，排水阀5的进水口与连接头4相连通，进气阀10与连接头4相连通，进气阀10可系统产生负压时实现进气功能，当有水压时进气阀处于关闭状态，当水温接近零摄氏度时，排水阀5自动开启，实现防冻。
对本实施例的排水结构的说明如下：
排水结构可在需要排水时自动进气，实现管路水的排空。进气阀10安装于排水结构的最高部位，一方面可以实现进气时从最高处进气，负压更明显，排水更顺畅，另一方面在无压差时，水不会自动流出。进气阀10的阀芯2通过自重实现开启，当有水压时，阀芯2在水压作用下向上运动实现关阀，当水压低到一定程度或者阀内产生负压时，阀芯2在自重及负压差力的作用下向下运动，实现开阀，从而实现进气。进气阀10与主管道41通螺纹连接，可实现维修和拆换功能，且无需将整阀拧下，方便更换和维修。
排水阀5直接连在连接头4的排水管道42上，节省管路空间，无需单独引出排水管。同时排水阀连接在排水管路上，能更好的感知排水管路的水温，排水阀启动温度更准确，可更精准的防冻，在水温低需要排水时及时排水，在水温高时防止漏水和意外排水。
在一些实施例中，排水结构具有温包52，温包52可感知温度，当温度降低到设定温度时，温包52缩短实现开阀，当温包52温度上升到设定温度时，温包52伸长实现关阀。设定开阀温度接近零摄氏度，可实现防冻需求。
参见图13至图19，本申请的实施例二的进气阀包括：阀座1，阀座1内具有进气腔12，进气腔12的两端分别为阀口121与排气口14；阀芯2，阀芯2可上下浮动地设置在进气腔12内，以封堵或者打开阀口121；阀芯2远离阀口121的一端设有与排气口14相对的连通槽22；阀芯2与进气腔12的侧壁之间存在流通通道3，阀口121、流通通道3、连通槽22以及排气口14可依次连通。采用上述设置，当进气阀的阀芯2在自重作用下打开进气通道11时，只需在阀芯2上设置连通槽22，并预留出阀芯2与进气腔12之间的流通通道3即可，进气阀结构简单。
具体地，本实施例可通过阀芯2与进气腔12侧壁之间通过间隙配合形成流通通道3，也可通过阀芯2外周设置凹槽或进气腔12侧壁设置凹槽形成流通通道3。
参见图13、图14，在本实施例的进气阀中，排气口14边缘设有阻挡部13，阻挡部13将阀芯2限位在进气腔12中。在本实施例中，设置可弯折的阻挡部13；使用时，阻挡部13可通过铆接对阀芯2进行限位，使得阀芯2装配简单。
在本实施例的进气阀中，参见图13、图14，阻挡部13可弯折；弯折前的阻挡部13为沿进气腔12轴线延伸的筒状，且阻挡部的内径大于进气腔12的内径，阻挡部13的内壁与进气腔12内壁形成台阶；弯折后的阻挡部13与阀芯2的底部止挡配合。
安装阀芯2时，首先使阀芯2通过阻挡部13中心的通道放入进气腔内，之后弯折阻挡部13，使阻挡部13采用铆接的方式对阀芯2进行限位，防止阀芯2从进气腔内脱落。采用上述设置，使得阀芯2的安装更加的简单。本实施例的台阶能够保证阻挡部13的弯折位置，避免阻挡部13弯折位置的不确定性造成对阀芯2的套牢。
在一些实施例中，进气阀的台阶设置在阻挡部13的铆接位置，可限定阻挡部13弯曲变形部位，避免阻挡部13在其他部位弯曲造成对阀芯2的套牢卡死。
参见图13至图15，在本实施例的进气阀中，阀座1包括：第一阀座体101，第一阀座体101内设有与阀口121连通的进气通道11；第二阀座体102，第二阀座体102与第一阀座体101连接，阀口121的至少部分设置在进气通道11内。
在本实施例的进气阀中，参见图16至图18，阀芯2远离出气口的一端具有与阻挡部13抵接的倒角部24。倒角部24能够进一步避免阻挡部13铆接后卡牢阀芯2，这样，能够对阀芯2起到防护的作用。
在本实施例的进气阀中，参见图16至图18，第一阀座体101和第二阀座体102之间具有第一安装槽15，第一安装槽15内设置有第一密封件16。
参见图16至图19，在本实施例的进气阀中，进气通道11为多个，多个进气通道11均与阀口121连通，多个进气通道11远离进气腔12的一端均设置有进气口111。
在本实施例的进气阀中，参见图16至图18，阀芯2包括：阀头201，阀头201可移动地设置，以封堵或者打开阀口121；阀体202，阀体202位于进气腔12中，阀体202与阀头201连接，阀体202与阀头201之间设置有第二安装槽25，第二安装槽25上设置有第二密封件23。
参见图16至图19，在本实施例的进气阀中，连通槽22设置于阀体；连通槽22为多个，多个连通槽22相间隔地设置；或者，连通槽22为多个，多个连通槽22之间相互连通。这样，能够提升进气阀的出气效率。
在本实施例的进气阀中，阀芯2由非金属材料制成。采用非金属材料制成的阀芯2，能够进一步地防止生锈情况的发生。
本实施例阀芯2通过与阀座1的侧壁之间的流通通道3实现流通，阀座1设有进气通道11；开阀时气体通过进气通道11，流经阀口121，再流经进气阀芯2，实现气体的进入；当需要关阀时，进气腔12压力大于外界压力，在关阀初期，进气腔12内水流先流经阀芯2的连通槽22，再经流通通道3流经阀口121，最后经进气通道11流出。当压差力不足时，阀芯2不足以克服自重和摩擦力，进气阀将一直排水，此时需要使压差建立在阀芯2上才能最大限度的利用内外压差力。因此进气阀在工作过程中，当阀口121处的流通能力小于进气通道11的流通能力时，水流的主要压降降在阀芯2上，使阀芯2能在更低的压差下实现关阀，从而防止水流过多的流出。阀芯2的材料重量越轻，关阀压差力越小，防止水溢出的能力越强。
操作简单，在阀芯2上只需设置连通槽22即可。
本实施例的进气阀通常安装到管路上，管路上同时安装防冻阀。当进气腔内压力较小时或者压力小于外界压力时，阀芯2在自重和压差力共同作用下向下运动，实现开阀，从而向阀内注入空气，空气进入管道内，避免管道内压力过小；在低温环境下，防冻阀自动打开，管道内的残留水经防冻阀排出。因此，本实施例的进气阀能够实现管道内外压力平衡，使防冻阀顺畅的排水。
在一些实施例中，进气阀设有阀芯2、阀座1，阀芯2上设有密封圈，进气阀芯下通过铆接实现限位，阀芯2底部设有连通槽22，阀座1上设有通孔，阀座排气口14的流通面积大于开阀时阀口121处的流通面积；阀座1铆接处设有台阶，可防止铆接时导向面变形导致阀芯2卡死。
在一些实施例中，进气阀芯2外径小于阀座1内径，通过阀芯2与阀座1的间隙实现流通。
在一些实施例中，进气阀头部设有O形圈槽，放置O形圈，密封更可靠。
从以上的描述中，可以看出，本申请上述的实施例实现了如下技术效果：
本实施例的进气阀当进气阀的阀芯2在自重作用下打开进气通道11时，只需在阀芯2上设置连通槽22，并预留出阀芯2与进气腔12之间的流通通道3即可，进气阀结构简单。
本实施例的进气阀设有可弯折的阻挡部13；使用时，阻挡部13可通过铆接对阀芯2进行限位，使得阀芯2装配简单。
本实施例的进气阀的台阶设置在阻挡部13的铆接位置，可限定阻挡部13弯曲变形部位，避免阻挡部13在其他部位弯曲造成对阀芯2的套牢卡死。
